Good morning !
First of all, sorry if my english is not great, I am a French native ... And i am a beginner with Labview.
I would like to filter a part of my noise using a FFT, multiplicating by an array of 0 and 1 which I chose myself, and then do a FFT-1.
I am aware there is straight forward filter solution implemented into labview, but I really wish to go my way.
My question is : I am a little lost into all the array possibilities. How can i design one which will have the number of line i decide (which I link with my sample), and a succession of 0 or 1 , without having to type 0 and 1 two hundred times ?
As a result, I just want to multiply the result of my FFt by this new array.
Thank you very much for your attention !
Solved! Go to Solution.

are all the ones adjacent?
If so, Initialize an array of zeros with the full lenght, the initialize a smaller array with all ones and use "replace array subset" to place it into the larger array at the correct location.

Yes all the ones are adjacent !
I see what you mean,it makes much more sense that what I was trying to do ...
I ll try it right now.
Thank you very much

There is also "Pulse Pattern" that might do what you want directly. 😄
